Beath High School - Int 1 Physics2 acceleration acceleration to collision air resistance average speed balanced forces collision how much the speed increases each second the frictional force which makes it difficult for a vehicle to move through air total distance divided by time equal and opposite forces acting on the same object this is when two objects hit each other and affect each others’ motion

Beath High School - Int 1 Physics3 force force to kilogram friction gravity instantaneous speed kilogram a push, pull or twist which causes an object to speed up or slow down. a force which opposes motion the attraction which a planet exerts on any object near it how fast something is moving at a moment in time the unit of mass

Beath High School - Int 1 Physics4 light gate light gate to metres per second squared (m/s 2 ) lubrication mass metres per second (m/s) metres per second squared (m/s 2 ) a lamp and a light sensor; used to measure speed making surfaces more slippery to reduce friction a measure of the amount of substance in an object the units of speed the units of acceleration

Beath High School - Int 1 Physics5 newton newton to skydiver newton balance range rebound skydiver the units of force apparatus for measuring forces the horizontal distance travelled by a projectile an object, like a ball, bouncing off a surface a person who falls freely through the air from a plane for a while before opening a parachute

Beath High School - Int 1 Physics6 speedometer speedometer to terminal velocity spoiler streamlined streamlining terminal velocity the instrument in a vehicle to measure its instantaneous speed a type of ‘wing’ on a car to make it more steamlined shaped to cut through the air (or water) more easily shaping an object to make it cut through the air (or water) more easily the fastest speed an object reaches as it falls through a fluid

Beath High School - Int 1 Physics7 weight weight to wind tunnel wind tunnel the force of attraction a planet exerts on an object a place where air can be blown over a vehicle to check how streamlined it is
